A switch device includes an operation switch including a switch knob formed integrally with a recess configured to allow a finger to be inserted. The operation switch includes a detector configured to detect a change in a physical amount caused by operation of the switch knob.

Provided is a novel dark-current-circuit interruption structure that can stably maintain the state of engagement of an engaging portion of a conductive component holder with an engaged portion of a case, while reducing the size of the case, and an electrical junction box including the same. A conductive component is formed by a plate metal fitting, a conductive component holder 48 includes elastic projecting pieces and engaging portions that are provided on each of a pair of side walls that are opposingly positioned with a gap between the plate metal fitting and each of the side walls, and the case includes engaged portions with which the engaging portions are to be engaged. When attaching the conductive component holder to the case, the engaging portions and the engaged portions are configured to come into contact with each other to cause the elastic projecting pieces 68 and 76 to elastically deform.

A device for limiting movement of an operator of at least one switch of a light fixture can include a body. The device can also include at least one fixture coupling feature disposed on the body, where the at least one fixture coupling feature is configured to couple to at least one device coupling feature of the light fixture. The body, when coupled to the light fixture, can be configured to limit the movement of a first operator of a first switch of the at least one switch.

A switch module includes an outer shell, a button and a bracket. The button is disposed to the outer shell. The button has a base board. One side of a bottom surface of the base board is recessed in the upward direction to form an avoiding groove. A rear of the bottom surface of the base board protrudes in the downward direction to form a driving pillar. The bracket is disposed under the button. A top surface of the bracket is recessed in the downward direction to form an accommodating groove. A top surface of a bottom wall of the accommodating groove is defined as a stopping surface. The driving pillar projects beyond the stopping surface. A front end of the top surface of the bottom wall of the accommodating groove is recessed downward to form an avoiding plane.

An illuminating light switch with an integrated sliding member that, when actuated by a user, exposes led lighting elements to illuminate the area where the light switch is affixed. The light switch includes a front member having a light aperture aligned with a light source, a rear member with a first mounting member affixed, a second mounting member adapted to be coupled to both a support surface and the first mounting member, and an internal switch to selectively supply current to the light source. In the closed position, the sliding member obscures the light source and no current is supplied to the light source. In the intermediate position, the sliding member partially exposes a first extent of the light source that provides illumination through the light aperture. In the open position, the sliding member exposes a second extent of the light source to provide a greater amount of illumination through the light aperture.

A touch-sensitive dimmer, configured to be electrically coupled to an illumination load to adjust an illuminance of the illumination load. It includes a hollow body, a power source printed circuit board assembly (PCBA) disposed inside the body, a control PCBA, and a touch-sensitive display panel, touch-sensing components and a display element disposed on the control PCBA. The display element displays changes of illumination load adjustment modes based on trigger signals generated by the touch-sensing components. The touch-sensitive display panel includes touch keys which correspond to the touch-sensing components and a display window which corresponds to the display element, and is assembled with the control printed circuit board assembly. The touch-sensitive dimmer combines touch-sensing functions and display screen functions to achieve intelligent control. By incorporating a wireless communication module, the dimmer can further achieve remote by a remote control device.
